Materials Data on Cr(FeTe2)2 by Materials Project
Abstract
Cr(FeTe2)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cr3+ is bonded to six Te2- atoms to form CrTe6 octahedra that share corners with six equivalent FeTe6 octahedra, edges with two equivalent CrTe6 octahedra, and edges with six FeTe6 octahedra. The corner-sharing octahedra tilt angles range from 6–8°. All Cr–Te bond lengths are 2.77 Å. There are two inequivalent Fe+2.50+ sites. In the first Fe+2.50+ site, Fe+2.50+ is bonded to six Te2- atoms to form FeTe6 octahedra that share edges with four equivalent CrTe6 octahedra and edges with six FeTe6 octahedra. There are a spread of Fe–Te bond distances ranging from 2.59–2.63 Å. In the second Fe+2.50+ site, Fe+2.50+ is bonded to six Te2- atoms to form FeTe6 octahedra that share corners with six equivalent CrTe6 octahedra, edges with two equivalent CrTe6 octahedra, and edges with six FeTe6 octahedra. The corner-sharing octahedra tilt angles range from 6–8°. There are a spread of Fe–Te bond distances ranging from 2.72–2.76 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a rectangular see-saw-like geometry to one Cr3+ and three Fe+2.50+ atoms. In the second Te2- site, Te2- is bonded to two equivalent Cr3+more »
